With gas prices absolutely sky-rocketing throughout the entire world, companies are starting to build more and more fuel efficient cars. Supercar companies are starting to resort to drastic measures, like building hybrids and diesels, since governments are starting to deploy laws that every car company has to build an “eco” and more fuel efficient version of their supercars. But for some reason, the Italians haven’t been affected by this law by the looks of their naturally aspirated 6.5 liter V12 in the new Lamborghini Aventador. Gotta love the Italians.

So with all that said, it’s time to look at the top 10 worst fuel-efficient/economic/planet polluters/modern production cars in the world. Don’t be surprised if you don’t see a car built from the past couple years.

Number 10: Choosing a number ten spot was a real challenge because there are a lot of cars with the same fuel economy in this category. We guess 11 mpg city and 17 highway is a target for most manufacturers such as Porsche, Aston Martin, and other car makers. You can choose which car you would like to see in this spot.

Number 9: The Ferrari 599 GTB Fiorano is going to be the first car on our list, meaning it’s the most economical car here. With 11mpg city (21l/100km) and 15 mpg highway (16l/100km), saying this is economic is like saying eating a block of butter is a healthier alternative than eating rat poison, it can still kill you, but not as instantaneous. Not that this Ferrari can kill you, but it will definitely put a dent in your bank account.

Number 8: For the number eight spot we had a couple of ties. But the car most fitting this spot would be the most expensive one with a bigger engine. The Mercedes-Benz ML63 AMG, has a 6.2 liter V8 engine that produces 510hp and 463lb-ft of torque. It does 0-60mph in a flat five seconds. When cruising along “economically”, it does 11mpg city (21l/100km) and 14mpg highway (17l/100km). That, considering a lot of factors, isn’t too bad compared to the rest of our list. Hang tight!

Number 7: Sticking to the Mercedes-Benz SUV family, our number seven spot has the G55 AMG in it. With it averaging an equal 11mpg city but a worst 13mpg highway (18l/100km), we don’t think anyone is going to be going for these cars anytime soon unless they have a private oil reserve underground in their backyard. This car has a 5.4 liter supercharged AMG V8 under the hood.

Number 6: Coming out of the Mercedes-Benz category, we enter the Bentley Continental GT Convertible. This 6.0 liter V12 does ten mpg city (24l/100km) and a not so bad 17 mpg highway (14l/100km). Look on the bright side, it’s a convertible. Oh wait, that actually makes it worst.

Number 5: At a cost of $ 335,500, our next car isn’t what we call cheap, nor light, nor small, and certainly not built with economy in mind, and if it was, it failed. The Maybach 57 has a 6.0 liter V12 that does ten mpg city and 16 highway (15l/100km). Then again if you think about it, this behemoth was built with the utmost luxury in mind, which the owner of the vehicle is either in the oil business or has a half eaten fruit as his company logo.

Number 4: When you start seeing more Italian names in our list, you know that we’re starting to make some progress now. The Ferrari 612 Scaglietti has a 5.7 liter V12 capable of chucking out 533hp. This V12 does nine mpg city (26l/100km) and 15 mpg highway (16l/100km). It’s certainly not the most economic car out there is it?

Number 3: In our number three spot we have the Bentley Azure Brooklands. This one was a tie with the Scaglietti if you look at the fuel consumption, but the estimated yearly fuel cost of the Brooklands is $ 4,568, compared to the yearly of fuel cost of the Ferrari at $ 4,377.

Number 2: In our second spot, we have a hypercar that surely isn’t a surprise to any of us. The 8.0 liter W16 engine of the mighty Bugatti Veyron does an insane eight mpg city (29l/100km) and and equally astonishing 14 mpg highway (17l/100km). These obviously aren’t necessarily numbers to be too proud of, but with an engine of that size accompanied by four turbochargers and ten intercoolers, there has to be some extreme sophistication in the engineering of this car for it not to be in our number one spot.

Number 1: In our number one spot of gas guzzlers, we have the raging bull of Italy, the Lamborghini Murcielago. With an average consumption of eight mpg city and 13 mpg highway (18l/100km), as Top Gear UK host Jeremy Clarkson would say, “the eco-mentalists would be happier if this car was running on sliced dolphins”.

Having cars like these is just insane and a waste of money if you think about it logically. And that’s why these cars are incredibly fun to have and talk about, because these are numbers you can shove into people’s faces with their “65 mpg eco friendly” toys. Don’t forget one thing though, at the end of the day, it’s not down to what kind of a car you have, rather it’s down to how you drive it. You can get the same numbers in a VW Polo diesel of a G55 AMG if you don’t drive it properly.

  1. dinosaurs, so obsolete. Cars like Tesla Model S and Model X are the future. Also just wait for 2015 nextgen Tesla Roadster with better batteries, a proper top speed, extremely low center of gravity etc. FU OPEC ;)

  2. Interesting but complete rubbish! Those results are total mess.. As Jeremy said one day, it is more about how you drive the car, not just some numbers from the factory or stupid reviews.. 612 (that can do about 20mpg on highway) in front of 599 and Veyron behind 640? Come on..

  3. The extreme depreciation on the 612 Scaglietti makes up for the gut wrenching fuel economy. On the other hand the LP640’s 12 cylinder should be ashamed that its at the bottom while the Enzo derived 599 V12 is on top.
